In order to create an item, players require schematics, which can be acquired in one of a few ways. Schematics can be learned from trainers, or they can be gained by reverse-engineering an item to discover what makes it tick. If you're the sneaky, saboteur type, you can even steal schematics from other factions and turn the enemy's own tools against them.
The page features myriad details on all of the available professions, but perhaps most interesting is the new information about the oddball Soldier for Hire. The Soldier for Hire is not a crafting profession in the strictest sense but rather is more like a bounty hunter who can sell his services through an in-game interface. The new page reveals that players will have good reason to hire a Soldier for Hire over some random schmuck, as the Soldier will have access to gear and weapons exclusive to the profession.
